Kernel Extensions Not Working

[Moduliz0r]

Hi

I've started getting two problems loading system extensions lately.

When I start up OSX86, I get these messages:

 

The system extension “/System/Library/Extensions/AppleHDA.kext/Contents/PlugIns/IOHDAFamily.kext“ was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update.

 

and

 

The system extension “/System/Library/Extensions/AppleHDA.kext/Contents/PlugIns/AppleHDAController.kext“ was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update.

 

Can anybody help me fix this? This could also be the answer to part of my no audio problem...

Your permissions are incorrect. Open up terminal and paste the following:

sudo chown -R root:wheel /System/Library/Extensions/AppleHDA.kext
sudo chmod -R /System/Library/Extensions/AppleHDA.kext

That should fix the problem.

Thanks,

but, chmod to what?

 

I get "usage: chmod [-fv] [-R [-H | -L | -P]] [-a | +a | =a [# [ n]]] mode|entry file ..." on the chmod.

 

Sorry, I'm a noob at OSX86/any UNIX/UNIX Like systems...

 

 

Edit:

Wait - i've rebooted and had no complaints

 

Thanks again

if you want todo it without typing in terminal you can download this kext helper

it set permissions for your extensions folder, and touch extensions folder, so cache files are rebuild on next boot.
